[TYPO3-dev] hash field in sys_refindex table

[Tim]

Hi

I have a script that needs to insert ~1200 content (tt_products list) 
elements to the tt_content table. The content has a starting point, 
which needs a row in sys_refindex.

I noticed that I can produce a random hash (non existant in the table 
ofcourse), and it will still work, but I would rather know the proper 
way to generate the hash.

I haven't got XDebug running currently, so if anyone could help me 
tracking down the code that produces the hash, or give me a safe-random 
hash generator, I'd really appreciate it.
